Diamond Eye 4" Turbo-Back Exhaust System (w/o Tip)

Diamond Eye has been in the diesel truck exhaust game a long time, and they've used their knowledge and experience to come out with an advanced 4" Turbo-Back Single-Exit Exhaust System that can give your Super Duty a nice boost in power, fuel economy, and a great sound. Diamond Eye's 4" Turbo-Back Kit gives your Super Duty an aggressive look while producing a mean rumble that will instantly catch everyone's attention. Diamond Eye's large 409 Stainless Steel tubing, unique muffler, and more efficient manufacturing enables this system to breathe new life into your F250 or F350 truck.

4" Diameter Mandrel-Bent Exhaust Tubing

This aggressive Diamond Eye Single Exit Turbo-Back Exhaust Kit bolts on right in place of your truck's factory exhaust system in an easy installation that can take less than an hour. The Diamond Eye kit features 4" diameter tubing that's all mandrel-bent to give your truck extreme exhaust outflow and reduce the factory stock restrictions. The kit is made out of 409 Stainless Steel and comes standard with a high-performance muffler that produces a deep, throaty, and aggressively loud tone to give your truck a great sound to go along with all that power. 409 Stainless Steel is a great option for trucks in wet environments where corrosion can be an issue. The kit comes with both hardware and detailed instructions for installation.

Will this kit work on my 04 6.0 excursion? Will it also be legal to use in California if I retain the catalytic converter and does it utilize the same hangers form my stock exhaust or does it come with its own? Thanks.

According to Diamond Eye, this kit will only fit F250 and F350 6.0L Powerstrokes, and is not CARB-Approved for street use.

Is the pipe 4" all the way to the turbo? Is the muffler loud? I'm needing a system to lower EGT's for towing with 05 f250 6.0

This kit does neck down to fit the stock catalytic converter, so it's not 4" diameter all the way through. The muffler included in this kit is louder and more aggressive than stock, though not as loud as a straight-pipe system, and the fact that the kit keeps the stock converter keeps sound down a bit, as well.
